Great Lakes GLFA AR15 450 Bushmaster | 18″ SS Barrel

The Great Lakes GLFA AR15 in .450 Bushmaster is a semi-automatic modern sporting rifle built around a billet 7075 aluminum platform and finished in white Cerakote. It ships with a single 5-round detachable Lancer magazine and an included muzzle brake. This configuration is intended for hunters and outdoorsmen who want a compact, rifle-caliber AR platform for short- to medium-range big-game applications.

For optics, a low-power variable such as the Vortex Viper PST Gen II 1-6×24 (priced under $1000) pairs well with this rifle, offering rapid target acquisition at close range and usable magnification for moderate-distance shots.
